Objective To study the correlation between serum cystatin C ( Cys C) and mean glomerular volume ( MGV), and seek for an ideal test marker of glomerular filtration rate.

Based on the method of characteristics and the theory of MGV, an application software of this numerical simulation with the effect of MGV is developed, which is being applied in the engineering practical.

本文基于水力瞬变的特征线法和MGV装置的原理，给出了带MGV装置的抽水蓄能过渡过程仿真计算框图，并开发出了相应的通用程序，在工程实践中得到了初步的应用。

While MGV are not on work, different closure law of guide vanes and different closure rates have much different effects on the phenomenon of two pressure peaks of casing pressure.

MGV装置未投入时，不同导叶关闭规律以及不同关闭规律斜率对蜗壳进口压力双峰特性的影响；

Meanwhile, MGV can low the maximum casing pressure.

MGV装置降低蜗壳进口压力最大峰值的作用。

The full name of polyurethane foam is one-component polyurethane foam sealant ( referred to OCF), which is a widely used chemical product with environmental protection and energy saving.

Liquid nitrogen or helium can expand by factors of 700 ( LN2) or 780 ( LHe) to normal temperature, and the uncontrolled releasing into an enclosed space can cause on oxygen deficiency hazard ( ODH).

低温液氦或液氮气化到室温环境后体积将膨胀700（LN2）的780倍（LHe），不加控制低温气体泄漏到房间中会引起氧气缺乏事故。

With the increasing desire of butene, the n-butane oxidative dehydrogenation ( ODH) being as a vital reaction of the selective oxidation has drawn more and more attention throughout of the world.

随丁烯需求量的日益增加，正丁烷氧化脱氢作为其中的一个重要反应，越来越受到重视。

As a vital reaction of the selective oxidation, the oxidative dehydrogenation ( ODH) of n-butane is becoming increasingly important not only in academic research but also in industrial utilization.

正丁烷氧化脱氢作为其中的一个重要反应，不论在理论研究还是在工业应用方面均具有重要意义。

The activated surface oxygen and oxygen vacancy from CeO2-CNT composites play an important role in two-step ODH reaction by promoting reverse water-gas shift reaction.

对于碳纳米管内负载CeO2催化剂，活化的表面氧和氧空穴在这个两步脱氢中通过促进逆水汽反应承担重要的作用。
